I provided at one time Windows build instructions to Ted Roth for avr-
libc. AFAIK he still has it, but it is yet to be put in to the avr-
libc docs.

But here:
is a really good source from Tony Mahar to get one started.

Cygwin is NOT needed. MinGW / MSYS however is needed. There are DLL
issues if one builds under Cygwin.

CAUTION! The instructions on Tony Mahar's web site (above) is good
for building binutils. Currently there is an extra requirement if one
is planning to build GCC as there is a bug in MSYS. However, this
should not affect alpha testing of Jörg's patch as it has to do with
binutils only.
